March 14 is Pi Day because the date (3/14) contains the first three digits of the number pi, or , the ratio of a circle’s circumference to its diameter.

But if we’re being honest, most people don’t get excited about Pi Day because they loooove geometry—they celebrate the holiday because it is a great excuse to eat pie. It’s also a great excuse to enjoy these historic photos of people making, serving, or eating pie.
